Lactobacillus strains are a major part of the probiotics, microflora of the intestine and of fermented dairy products, and are found in a variety of environments. The aim of this study was to find out the ability of bile and acid tolerance and antibacterial properties of the twenty eight isolates of three group lactobacilli namely Lactobacillus plantarum, Lactobacillus casei and Lactobacillus d...

We report the draft genome sequence of the type strain Lactobacillus pasteurii CRBIP 24.76, which is closely related to L. gigeriorum CRBIP 24.85(T), isolated from a chicken crop. The total length of the 29 contigs is about 1.9 Mb, with a G+C content of 40% and 1,946 coding sequences.

Streptococcus mutans contributes significantly to dental caries, which arises from homoeostasic imbalance between host and microbiota. We hypothesized that Lactobacillus sp. inhibits growth, biofilm formation and gene expression of Streptococcus mutans. Antibacterial (agar diffusion method) and antibiofilm (crystal violet assay) characteristics of probiotic Lactobacillus sp. against Streptococc...

In this study the growth of genetically modified Lactobacillus casei LAB6, overexpressing proline iminopeptidase PepI and its capacity to increase free proline was investigated during ripening of Edam cheese. The strain successfully survived 12 weeks of ripening period in cheese. The food-grade plasmid pLEB604, carrying the pepI gene, was stable, and PepI enzyme was active in LAB6 cells isolate...

Gut microbiota was analyzed in children, aged 6-18 months and suffering from atopic dermatitis before and after 3 month supplementation of their diet with Lactobacillus casei DN--114001 in a dose of 109 cells daily. On completion of this period the total number of fecal Lactobacillus sp. cells decreased from 7.86 Log10 CFU/g to 6.40 Log10 CFU/g. After the next 5 months (without dietary suppleme...

Here, plantaricin UG1 was shown to inhibit Listeria monocytogenes LMG10470 (L. monocytogenes) cells. The inhibition was not caused by lactic acid produced by the bacteriocin producing strain Lactobacillus plantarum UG1 (Lact. plantarum). Partially purified plantaricin UG1 had a higher antilisterial activity than Lact. plantarum cells in both Zabady and Kareesh cheese samples during their matura...
